Project summary

Edit project overview to modify the project summary.

The Jufferbeek is a very small stream with an irregular discharge. It is a tributary of the Deurningerbeek and Regge. Parts of the stream are still meandering, but other parts, that are close to urban or industrial areas, have been straightened. In 2006, dead wood was introduced in this stream. The purpose of this exercise was to restore the circulation of organic detritus and provide a habitat for particular species. It was also meant to raise the streambed and increase the retention capacity.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Water levels downstream of the wood packages are higher and fluctuate more downstream of the wood package. This may be caused by the increased flow resistance due to the dead wood, leading to a higher water level for the same discharge. Water level peaks downstream of the wood package are smaller relative to the average water levels. This may because of water retention by the wood packages. As a result of the introduction of dead wood, sandy substrates have become less dominant and silty substrates have become more prominent. No change in nutrient levels was observed. A change in species composition was observed, but this change was short-lived. A subtle change in macroinvertebrate composition remained for a longer period afterwards.
